Group Structure
Mitsui Sumitomo Insurance Co., Ltd. sits 1 level below its ultimate parent, MS&AD INSURANCE GROUP HOLDINGS, INC., registered in Japan. 29 subsidiaries are recorded beneath it, across 14 jurisdictions. The full chain up to MS&AD INSURANCE GROUP HOLDINGS, INC. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Mitsui Sumitomo Insurance Co., Ltd.'s own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 29 subsidiaries span Japan, United Kingdom, Taiwan, Singapore, Switzerland, China, and 8 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. 10 of the 29 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
